Abstract: The present invention relates to a working machine having an engine room and a housing, wherein the housing at least partially surrounds or can surround the engine room, wherein a venting space, in which a line mouth of a line ends, is arranged on the housing, wherein the venting space is delimited from the engine room, preferably delimited in a gas-tight manner, and wherein the venting space is formed by a partial region of the housing and a bottom piece arranged in the engine room.

Abstract: The present invention relates to a work machine, in particular a wheeled loader, having an electric motor and having oil cooling that is suitable and intended to cool the electric motor and having a driving axle that has an oil reservoir, wherein a feed line from said oil reservoir to the electric motor and a discharge line from the electric motor to said oil reservoir are present and a pump is present to pump oil from the oil reservoir to the electric motor so that the electric motor is cooled by means of oil from the oil reservoir of the driving axle.

Abstract: The invention relates to a system for controlling a work machine, in particular a wheel loader, having at least one hand-held control device (6), in particular a joystick or steering wheel, at least one restoring device (8) in the form of one or more spring assemblies, which are connected to the hand-held control device in such a way a restoring force is exerted upon the hand-held control device by the spring assembly when said spring assembly is not in the central position. An adjusting device (9, 12, 13) which engages with the spring assembly such that an adjustment of the central position of the spring assembly can be carried out, is provided.

Abstract: The present disclosure relates to a system for detecting axle loads of a vehicle, in particular of a wheel loader, comprising a sensor for determining the torque of a drivetrain and a second sensor for detecting the load of an axle, wherein the second sensor is arranged on a non-rotating component of the axle.

Abstract: The lifting frame with Z-kinematics of a wheel loader comprises an accessory arm with a lifting cylinder coupled to the vehicle frame or to the truck front-end and a rocker-type reversing lever coupled to the accessory arm, to the ends of which reversing lever the tipping cylinder and the connecting link are coupled for the swivelling of the attachment. Attachments, e.g. a bucket or a log loader, are mountable on the lifting frame. In order to be able, in a raised position of the lifting frame, to swivel the attachment with the necessary large moment from a position tipped downwards into a position tipped upwards, without any reinforcement of the tipping cylinder, there is coupled with the lifting frame, in the direction of the attachment in front of the articulated joint connecting the tipping cylinder to the vehicle frame, at least one hydraulic cylinder, whereof the piston rod engages in an articulated manner with the swivel axle connecting the reversing lever with the tipping cylinder.
